physics612  Accelerator Physics
We 10-12, Th 10-12, SR I, HISKP
  Instructor(s): W. Hillert, A. Lehrach, R. Maier
  Prerequisites: Mechanics, Electrodynamics
  Contents: Die neuere experimentelle Physik basiert zum Teil auf dem Einsatz von
Teilchenbeschleunigern, insbesondere im Bereich der Hochenergiephysik, der
Materialforschung und der Erforschung der Substruktur der Atomkerne und der
Hadronen. Durch die aktuellen wissenschaftlichen Fragestellungen wurden und
werden auch weiterhin ständig gesteigerte Herausforderungen an den Betrieb und
die Entwicklung von Teilchenbeschleunigern gestellt, was zum Einsatz
modernster Technologien aus einer Vielzahl von physikalischen Bereichen führte
(als Beispiele mögen hier die Realisierung einer ca. 27 km langen, fast vollständig
supraleitenden Anlage am CERN / Genf oder der Aufbau eines mehr als
3 Kilometer langen 1-Angström Röntgenlasers am DESY / Hamburg dienen). Im
Zuge dieser Entwicklungen und systematischen Untersuchungen der physikalischen
Vorgänge in Beschleunigern entstand die Beschleunigerphysik als eigenständiger
Fachbereich der angewandten Physik.

Die vorliegende Vorlesung ist eine Einführung in die Beschleunigerphysik. Sie
gibt einen Überblick über die verschiedenen Funktionsweisen unterschiedlicher
Beschleunigertypen und führt, neben einer physikalischen Behandlung der
wichtigsten Subsysteme (Teilchenquellen, Magnete, Hochfrequenzresonatoren), in
die transversale und longitudinale Strahldynamik ein.

More recent experimental physics is partly based on the use of particle
accelerators, especially in high energy physics, materials research and
exploration of the substructure of atomic nuclei and hadrons. Due to the
current scientific questions, more and more demanding challenges have been and
still are posed to the operation and development of particle accelerators,
thus leading to the use of state-of-the-art high technology taken from a
multitude of fields in physics (as examples may be cited the realisation of a
27 km, almost entirely superconducting facility at CERN / Geneva or the
construction of a more than 3 kilometers long 1 Angström X-ray laser at DESY /
Hamburg). In the course of these developments and systematic investigation of
the physical processes in particle accelerators, particle accelerator physics
emerged as a stand-alone field of applied physics.

The present lecture is meant as an introduction into particle accelerator
physics. It provides an overview of the various functional principles of
different accelerator types and provides, alongside a physical treatment of
the most important subsystems (particle sources, magnets, resonant cavities),
an introduction into transversal and longitudinal beam dynamics.

physics719  BCGS intensive week (Detectors and Physics of Higgs Discovery Machines)
24.09.2012 - 28.09-2012
  Instructor(s): E. von Törne
  Contents: This course will of interest both for students starting their master studies, students who start their master project soon, Ph.D. students from other fields of physics who wish to broaden their horizon. The BCGS intensive week aims at providing a detailed insight of an LHC detector and the experiments that are done with them to address important questions of fundamental physics today. Emphasis is put on the recent discovery of a new particle by the ATLAS and CMS experiments which is probably the Higgs boson.

About half of the course is devoted to hand-on projects. Students have the choice between two topics:

  • C++ in high energy physics

  • FPGA (hardware-near programming)

What does one need to know to built such detectors and to analyse LHC data? While following these lines, particular emphasis is given to
- the scientific and technical requirements of LHC detectors
- the physics of tracking and energy detectors
- the theoretical background of LHC physics (Standard Model + Higgs physics)
- the experimental methods to address these physics questions
Of course, not all topics can be addressed to depth within one week. Thus an effort is made that students will receive an overview and understand the most important mechanisms.
  Comments: see web page http://www.uni-bonn.de/~etoerne/teaching/intensive-week12/
The course is an all-day workshop 24.-28. September, starting at 9:15. Studnets from Cologne: There is a regional train at 8:38 from Köln-Süd that would bring you to Bonn in time for the lecture. This train is free with the student ticket.

astro856  Quasars and microquasars
Do 13-15, Raum 0.01, MPIfR
  Instructor(s): M. Massi
Stellar-mass black holes in our Galaxy mimic many of the phenomena seen in quasars but at much shorter timescales. In these lectures we present and discuss how the simultaneous use of multiwavelength observations has allowed a major progress in the understanding of the accretion/ejection phenomenology.


Stellar evolution, white dwarf, neutron star, BH
Accretion power in astrophysics
Nature of the mass donor: Low and High Mass X-ray Binaries
Accretion by wind or/and by Roche lobe overflow
